53 vmax, win case, cci 400, 25g Benchmark =1/2 moa at 3200 fps from my 20" RRA predator pursuit. Also shoots 1/2 moa and 3200 fps from my 21" pac-nor barreled 223 AI as a fire forming load.

I have also found that in fire formed 223 AI brass with a cci no.41 primer 27.5g of benchmark and a 53 Vmax does 3500 fps and shoots 1/2 MOA. Both guns are 8 twists so I have no problems stabilizing them and they still make it to the target. For years I loved the 50g Vmax but I've been buying the new 53's lately.
